Yes, one of history’s favorite First Ladies once called this Upper East Side place home. In fact, she wrote about her apartment in a column she had, called “My Day,” referring to it as her “new little apartment.” Today the building, part of the landmarked Treadwell Farm Historic District, is a single-family townhouse owned by investor Charles Ueng. He purchased it for about $9 million in 2011, spent $2 million renovating it, and now has it on the market for $18 million.
